Summary

Built in 1963 by the USDA NRCS, this earth dam stands at a height of 15 feet and spans 425 feet in length, with a storage capacity of 165 acre-feet. The primary purpose of this dam is to provide fire protection, stock, and recreation opportunities in addition to supporting fish and wildlife habitat.

Despite its low hazard potential, Ponderosa has a moderate risk assessment rating of 3, suggesting potential vulnerabilities in the event of extreme weather events or other emergencies. The dam is equipped with an uncontrolled spillway with a width of 100 feet, capable of handling a maximum discharge of 1303 cubic feet per second. As of now, the dam's condition assessment is listed as "Not Rated," indicating a need for further evaluation to ensure its continued safety and functionality.

For water resource and climate enthusiasts interested in the management and conservation of dams like Ponderosa, this site serves as a valuable example of a multi-purpose structure that supports both ecological and recreational objectives. With its location in a rural area and its importance for wildlife and water management, Ponderosa represents a unique opportunity for studying the intersection of human infrastructure and natural ecosystems in the context of sustainable water resource management.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
